To all whom t may concern.'

Be it-known that l, Francis A. Nouan, a citizen of the United States, residing1 at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful improvement in Resilient Shoe-Heels, of which the following is a specification, this application being a division of my application for patent tiled by me on the 26th day or November, 19in, bearing Serial Number .An object of this invention is to provide a resilient shoe heel for permanent attachmentto a shoe in such manner as to mosty efectively prevent the collection of moisture and dirt in cavities or openings which lhave been formed in the heel. More particularly the novel features of this invention claimed i in this application relate to the cushioning means employed and the sealing); means for preventing moisture and dirt entering between the heel and the shoe.

A further object is to so construct the heel as to most effectively preventslipping on the ground. This application is a division of the subject matter set forth in my coun pauion application.,v Serial Number 63,353,

lile'd on Nov. 26, 1915, torfshoe heel. To these ends my invention comprises the features ofy construction and combination of parts hereinafter described and set forth in the claim.v

in the accompanying' drawing 'forming par of this specification, Figure l is 'a side elevation of a detail of a shoe, a portion of the heel thereof being' shown in section; Fig. 2 is a top plan view; Fig, 3 is a section talren on the line X- of Fig. 2; Fig. l is ann other section taken on the line Y--Y or Fig. 2, and Fig. 5 is a top plan oi an alternative construction.,

lin the' drawing' A. indicates a detail of a shoe or boot, it beine' understood that vihere ,mannen which is adapted for permanent attachment p the term ,shoe is used throughout the specification and in the claim following', it is intended to be construed as meaning` boots.,` shoes, or anyother tout wearinp;4 apparel with which resilient `heels are adapted for use. The shoe A is shown with a portion oli the yusual heel 2 secured to the lift `in the usual B ism'y improved resilient heel,

to the heel portion' l2` of the shoe or, when desired, it may bepernianently ScCured directly to the lift instead of tothe heel portion. My improved resilient heel B may be made out ot rubber or other resilient material and is molded or otherwise formed in the shape of the usual heel. The body B of the heel is formed with a cavity 3 in the topside thereof adjacent to the lower surliace of the heel portion 2. rllhe rim or margin l of the heel surrounding the cavity 3 has embedded in its upper portiona plurality of Washers 5,

which are suitably spaced apart and through which fastening devices such as nails 6 are driven from the lower side of 'the resilient heel upwardly into the body of the heel portion 2 of the shoe. `Suitable buttresses G are vformed on the heel B projecting into the or heel face 8 of the resilient heel beine;P

concave. When the resilient heel is secured with its Wear surface outermost upon the shoe,the fastening devices hold the heel with its margin compressed-tightly. against` the shoe heell or lift, thereby producing a close joint under compression and causilflgrr the heel to compress tightly against the surface upon which it is mounted..- llhe mangi# nal edge -7 surrounds the entire heel and lies in asingle plane, thereby assisting in caue- .ing the heel to adhere by. suction in place.

rllhe outer The body oit the resilient heel 1s formed with columns 9 in the cavity 3, which pro# ject upwardly and press ,tightlyagainst the surface 1Q, which maybe of the heel portion or lift upon which theheel is mounted. The columns 49 when the resilient heel B ie secured on the lower :tace (treadiace) l0 ed' lll() the oldlreel or pad'of the shoe impress tilleul-52.` y

selves against the lower resilient tread tace` ot the heel B and carry alarga portion ot 'the superimposedload'. 'lhe load' isv thus sustainedv in distinct spots or sonesA onv the tread or 'wear surtace `nounouuitthe re los lsilient heel B ldue to the heel being composed of rubber or other resilient material andl these spotsfor zones become friction spots or z'ones on the tread surface of the resilient heel B, which reduce and tend to'prevent slipping. When desired a single column 11 (see Fig. 5) can be employed instead of a plurality, the saineA result being accom- -vplished thereby to a diderent extent` In accordance with the patent statutes, I have described the principles of operation of my invention, together with the apparatus which l new consider to represent the best navegas claim as new and ters Patent is y,

An elastic-heel having a lower tread surface and an upper side, said lupper side being formed with a deep chamber surrounded by a laterally extending continuous surface portion and with an approximately cylindrical column of small diameter and terminating in the plane of the edge of said chamber to remain normally uncompressed, whereby a portion of the load of a person standing upon the heel is immediately carried by the column directly to the tread surface of the heel tending to'produce a small sharply dened friction zone onf the tread surface.

Inv-testimony whereof l have signed my name to this speoication.

FRANCIS A. NOLAN.
